Inuit communities are found in the Arctic, in the Northwest Territories, Labrador and Quebec in Canada, above tree line in Alaska (where people are called the Inupiat and Yupik), and in Russia (where people are called the Yupik people).
In the summer, when the snow melted, Inuit lived in tent-like huts made of animal skins stretched over a frame. Although most Inuit people today live in the same community year-round, and live in homes built of other construction materials that have to be imported, in the past Inuit would migrate between a summer and winter camp which was shared by several families.
